Description

COUVERCLE DE FERMETURE POUR RECIPIENT EQU IPE D'UN JOINT D'ETANCHEITE La présente invention concerne de manière générale les joints d'étanchéité pour couvercle de récipient équipé ou destiné à être équ ipé d'un moyen d'agitation.  The present invention generally relates to seals for container lids equipped or intended to be equipped with a stirring means.
L'invention concerne plus particulièrement un couvercle de fermeture pour récipient de liquide, ledit couvercle comprenant un passage d'axe permettant le passage à travers le couvercle d'un corps allongé d'un moyen d'agitation destiné à être monté rotatif dans ledit passage d'axe, ledit passage d'axe comprenant une partie dite de réception logeant un joint d'étanchéité annulaire destiné à être traversé par ledit corps allongé du moyen d'agitation. The invention more particularly relates to a closure cap for a liquid container, said lid comprising an axis passage allowing the passage through the cover of an elongate body of a stirring means intended to be rotatably mounted in said passage. axis, said axis passage comprising a so-called receiving portion housing an annular seal to be traversed by said elongated body of the stirring means.
Le joint d'étanchéité a pour fonction de permettre l'étanchéité entre le couvercle de fermeture et le corps allongé rotatif du moyen d'agitation qui traverse le couvercle. En particulier, le joint d'étanchéité permet d'éviter l'évaporation de vapeurs de solvant présents dans le liquide contenu dans le récipient, ainsi que les fuites dudit liquide par exemple pendant la rotation du moyen d'agitation ou au cours de manipulations du récipient en dehors de l'armoire de stockage. The function of the seal is to allow sealing between the closure cap and the elongated rotating body of the stirring means that passes through the cover. In particular, the gasket makes it possible to avoid the evaporation of solvent vapors present in the liquid contained in the container, as well as the leakage of said liquid, for example during the rotation of the stirring means or during handling operations. container outside the storage cabinet.
On connaît de l'état de la technique des couvercles tels que décrits ci-dessus comme l'ill ustre en particul ier le brevet EP-0.820.879. Cependant, les couvercles connus de l'état de la technique utilisent un simple joint à lèvre comme joint d'étanchéité. Un simple joint à lèvre ne donne pas entièrement satisfaction en ce qui concerne l'étanchéité du couvercle au niveau du passage d'axe traversé par le corps allongé rotatif du moyen d'agitation. Lids as described above are known from the state of the art as illustrated in particular in EP-0,820,879. However, the covers known from the state of the art use a simple lip seal as a seal. A simple lip seal is not entirely satisfactory as regards the sealing of the lid at the axis passage through which the elongated rotating body of the stirring means.
En outre, on observe qu'un simple joint à lèvre s'use prématurément au contact avec les éléments abrasifs présents dans le liquide contenu dans le récipient, ce qui rapidement ne permet plus au joint à lèvre d'assurer sa fonction d'étanchéité. In addition, it is observed that a simple lip seal wears prematurely in contact with the abrasive elements present in the liquid contained in the container, which quickly no longer allows the lip seal to perform its sealing function.
On remarque également que la partie ménagée dans le passage d'axe pour la réception du joint peut présenter des variations de cote qui entraînent un positionnement du joint annulaire dans le logement tel que l'axe de l'ouverture du joint annulaire est décalé par rapport à l'axe du passage d'axe, ce qui entraine un problème de centrage du corps allongé du moyen d'agitation au moment de son montage dans le passage d'axe à travers le couvercle. Le décentrage de l'axe du joint par rapport à l'axe du passage d'axe pose également des problèmes de serrage de la paroi interne du joint contre le corps allongé du moyen d'agitation qui le traverse et donc des problèmes d'étanchéité. La présente invention a pour but de proposer un nouveau couvercle équipé d'un joint d'étanchéité permettant d'améliorer l'étanchéité entre le couvercle et le corps allongé du moyen d'agitation, c'est-à-dire au niveau du passage d'axe ménagé à travers le couvercle. Un autre but de l'invention est de proposer un nouveau couvercle équipé d'un joint d'étanchéité permettant d'améliorer le centrage du moyen d'agitation par rapport au passage d'axe ménagé dans le couvercle au cours du montage dudit moyen d'agitation à travers le couvercle. Un autre but de l'invention est de proposer un nouveau couvercle équipé d'un joint d'étanchéité dont la conception permet de limiter l'usure dudit joint vis-à- vis des produits abrasifs contenus dans le récipient fermé par le couvercle. It should also be noted that the part formed in the axis passage for the reception of the seal may have dimensional variations which result in positioning of the annular seal in the housing such that the axis of the opening of the annular seal is offset relative to to the axis of the axis passage, which causes a problem of centering the elongate body of the stirring means at the time of its mounting in the axis passage through the cover. Decentering the axis of the joint with respect to the axis of the axis passage also causes problems of clamping the inner wall of the seal against the elongated body of the stirring means which passes through it and therefore sealing problems . The present invention aims to propose a new lid equipped with a seal to improve the seal between the lid and the elongate body of the stirring means, that is to say at the passage axis arranged through the cover. Another object of the invention is to propose a new lid equipped with a seal making it possible to improve the centering of the stirring means with respect to the axis passage formed in the lid during the mounting of said means for stirring through the lid. Another object of the invention is to propose a new lid equipped with a seal whose design makes it possible to limit the wear of said seal vis-à-vis the abrasive products contained in the container closed by the lid.
A cet effet, l'invention a pour objet un couvercle de fermeture pour récipient de liquide, ledit couvercle comprenant un passage d'axe permettant le passage à travers le couvercle d'un corps allongé d'un moyen d'agitation destiné à être monté rotatif dans ledit passage d'axe, ledit passage d'axe comprenant une partie dite de réception logeant un joint d'étanchéité annulaire destiné à être traversé par ledit corps allongé du moyen d'agitation, caractérisé en ce que la face périphérique interne dudit joint d'étanchéité annulaire comprend une lèvre hélicoïdale. To this end, the subject of the invention is a closure lid for a liquid container, said lid comprising an axis passage allowing the passage through the lid of an elongated body of a stirring means intended to be mounted. in said axis passage, said axis passage comprising a said receiving portion housing an annular seal to be traversed by said elongated body of the agitating means, characterized in that the inner peripheral face of said annular seal comprises a helical lip.
La lèvre hélicoïdale forme par ses spires une succession de barrières pour le liquide ce qui permet d'améliorer l'étanchéité dynamique du couvercle au niveau du passage d'axe. En particulier, si une spire de la lèvre est attaquée par le liquide, la spire suivante forme une autre barrière qui maintient l'étanchéité entre le passage d'axe et le moyen d'agitation qui le traverse. The helical lip forms with its turns a succession of barriers for the liquid which improves the dynamic sealing of the cover at the axis passage. In particular, if a turn of the lip is attacked by the liquid, the next turn forms another barrier which maintains the seal between the axis passage and the stirring means passing therethrough.
En outre, la réalisation de la lèvre d'étanchéité du joint d'étanchéité sous forme d'un filet hélicoïdal avec une pluralité de spires consécutives permet de limiter le serrage de la lèvre de chaque spire contre le corps du moyen d'agitation et ainsi de réduire l'usure du joint et du corps allongé du moyen d'agitation. In addition, the production of the sealing lip of the seal in the form of a helical thread with a plurality of consecutive turns makes it possible to limit the tightening of the lip of each turn against the body of the stirring means and thus to reduce the wear of the seal and the elongated body of the stirring means.
Une telle limitation de serrage, rendue possible par l'utilisation d'une lèvre hélicoïdale, permet de réaliser le corps rotatif du moyen d'agitation en une matière plastique chargée en verre qui est moins coûteuse que le métal mais plus abrasive pour le joint. Such a limitation of clamping, made possible by the use of a helical lip, makes it possible to produce the rotating body of the stirring means in a plastic material loaded with glass which is less expensive than the metal but more abrasive for the joint.
Enfin , u ne tel le conception d u joint d'étanchéité an n ula ire avec lèvre hélicoïdale permet de ne pas avoir à équiper le joint d'étanchéité d'anneau ressort au niveau de la ou des lèvres ou d'armature de maintien au niveau de la paroi extérieure du joint, ce qui limite le coût du joint et donc du couvercle. Finally, such as the design of the seal ring with helical lip allows not to have to equip the spring ring seal at the level of the lips or reinforcement at the level of the outer wall of the seal, which limits the cost of the seal and therefore the lid.
Le joint d'étanchéité permet ainsi d'assurer un niveau d'étanchéité aux fluides suffisant, en particulier pour l'ensemble des peintures utilisées en carrosserie automobile. Préférentiellement, le joint annulaire est un joint à deux parois périphériques reliées l'une à l'autre par une liaison souple. The seal thus makes it possible to ensure a sufficient level of fluid tightness, in particular for all the paints used in automobile bodywork. Preferably, the annular seal is a seal with two peripheral walls connected to each other by a flexible connection.
De préférence, lesdites parois dites respectivement interne et externe, sensiblement coaxiales, sont écartées l'une de l'autre et reliées l'une à l'autre par une liaison souple de type pont s'étendant, de préférence, à mi-hauteur desdites parois, dans le plan circonférentiel médian desdites parois. Preferably, said so-called inner and outer walls, which are substantially coaxial, are separated from each other and connected to each other by a bridge-type flexible link preferably extending at mid-height. said walls, in the median circumferential plane of said walls.
Avantageusement, les spires sont espacées axialement les unes des autres pour délimiter entre elles une gorge en hélice. L'orientation des spires du filet hélicoïdal est choisie de telle sorte que, pour un sens de rotation donné du moyen d'agitation , un éventuel l iqu ide présent dans la gorge en hél ice, délimitée entre les spires, est refoulé dans le récipient par rotation dudit moyen d'agitation. Advantageously, the turns are spaced axially from each other to delimit between them a spiral groove. The orientation of the turns of the helical thread is chosen such that, for a given direction of rotation of the stirring means, any liquid present in the helical groove delimited between the turns is pushed back into the container. by rotation of said stirring means.
La face périphérique interne dudit joint d'étanchéité comprend également une lèvre d'étanchéité circulaire située à proximité de la face d'ouverture du joint d'étanchéité annulaire opposée à celle destinée à être orientée côté récipient. Cette lèvre d'étanchéité circulaire réalise l'étanchéité statique aux vapeurs de solvant lors du stockage statique, ainsi qu'aux liquides lors des manipulations du récipient, la lèvre circulaire permettant l'obturation de la gorge en hélice délimitée par les spires du filet hélicoïdal. La lèvre hélicoïdale limite l'accès du liquide à la lèvre d'étanchéité circulaire, ce qui permet de limiter l'usure de la lèvre circulaire qui forme la dernière barrière d'étanchéité. En effet, le produit doit préalablement monter dans le filet avant d'atteindre la lèvre d'étanchéité. Ainsi, dans le cas de peinture abrasive, on obtient une usure plus progressive de la lèvre d'étanchéité circulaire, ce qui permet de prolonger significativement la durée de vie du produit. The inner peripheral face of said seal also comprises a circular sealing lip located near the opening face of the annular seal opposite that intended to be oriented container side. This circular sealing lip provides static sealing to solvent vapors during static storage, as well as to liquids during handling of the container, the circular lip allowing the closure of the spiral groove delimited by the turns of the helical thread. . The helical lip limits the access of the liquid to the circular sealing lip, which makes it possible to limit the wear of the circular lip which forms the last sealing barrier. Indeed, the product must first climb into the net before reaching the sealing lip. Thus, in the case of abrasive paint, a more gradual wear of the circular sealing lip is obtained, which makes it possible to significantly extend the life of the product.
En particulier, les produits abrasifs sont généralement visqueux et pénètrent ainsi de façon limitée dans le filet, de sorte que l'usure du joint d'étanchéité est limitée à une hauteur réduite. In particular, the abrasive products are generally viscous and penetrate thus in a limited way in the net, so that the wear of the seal is limited to a reduced height.
De préférence, ledit joint d'étanchéité annulaire est réalisé en un matériau thermoplastique, tel qu'un élastomère thermoplastique. Preferably, said annular seal is made of a thermoplastic material, such as a thermoplastic elastomer.
Selon une autre caractéristique avantageuse de l'invention, ledit couvercle est équipé dudit moyen d'agitation dont le corps allongé, tel que tige, est monté rotatif à travers le passage d'axe du couvercle et le joint d'étanchéité. According to another advantageous characteristic of the invention, said lid is equipped with said stirring means, the elongate body of which, such as rod, is rotatably mounted through the axle passage of the lid and the seal.
Préférentiellement, ledit corps allongé est équipé à, ou au voisinage de, une extrémité, d'au moins un organe d'agitation tel que pale et à, ou au voisinage de, l'extrémité opposée, d'une partie de prise pour l'entraînement en rotation dudit corps allongé du moyen d'agitation.

Ladite partie de réception 21 de joint d'étanchéité 1 loge un joint 1 d'étanchéité annulaire destiné à être traversé par ledit corps allongé 30 du moyen d'agitation 3. Ledit moyen d'agitation 3 permet de maintenir l'homogénéité du produit contenu dans le récipient, en particulier dans le cas d'un pot de peinture. Said cover 2 comprises an axis passage 20 allowing the passage through the cover 2 of an elongated body 30 of a stirring means 3 intended to be rotatably mounted in said axis passage 20 for the agitation of said liquid . Said axis passage 20 comprises, on the one hand, a so-called receiving portion 23 of the elongate body 30 to be traversed by the elongate body 30 of the agitate means 3, and, on the other hand, a so-called part receiving member 21 of seal 1, of inner diameter greater than the inside diameter of the receiving portion 23 of the elongate body. Said receiving part 21 of seal 1 houses an annular sealing gasket 1 intended to be traversed by said elongated body 30 of the stirring means 3. Said stirring means 3 makes it possible to maintain the homogeneity of the product contained in the container, especially in the case of a paint bucket.
Comme illustré à la figure 1 , le couvercle 2 selon l'invention est destiné à la fermeture d'un pot ou autre récipient 4 de liquide. Ce couvercle 2 est un couvercle de précision qui présente un bec 25 verseur à obturateur 26 coulissant sollicité par un ressort 24 du type à épingle à cheveux. Cet obturateur 26 est commandé en déplacement par un levier 27 d'ouverture pivotant. Ledit couvercle 2 est manipulé par l'intermédiaire d'une poignée 28 de préhension. Le récipient 4 et son couvercle 2 peuvent être logés dans une armoire de stockage d isposant d'un ou plusieurs emplacements de stockage dudit récipient. Chaque emplacement est équipé d'un moyen d'actionnement du moyen d'ag itation pour ag iter le l iquide par rotation du corps du moyen d'agitation. En particulier, ledit couvercle 2 peut être appliqué aux récipients dits suspendus au niveau de leur couvercle ou encore aux récipients posés dans une armoire d'agitation. Le couvercle est équipé de moyens de fixation au récipient 4. Avantageusement, le couvercle peut s'adapter à des boîtes de différents diamètres. As illustrated in Figure 1, the lid 2 according to the invention is intended for closing a pot or other container 4 of liquid. This lid 2 is a precision lid which has a pourer spout 26 with sliding shutter biased by a spring 24 of the hairpin type. This shutter 26 is controlled in displacement by a pivoting opening lever 27. Said cover 2 is manipulated by means of a handle 28. The container 4 and its lid 2 may be housed in a storage cabinet having one or more storage locations of said container. Each location is equipped with a means for actuating the agitate means for agitating the liquid by rotating the body of the stirring means. In particular, said lid 2 can be applied to so-called suspended containers at their lid or to containers placed in a stirring cabinet. The lid is equipped with means for fixing the container 4. Advantageously, the lid can be adapted to boxes of different diameters.
Dans le cas des récipients posés, le couvercle 2 est mobile en translation par rapport au corps allongé 30, appelé axe, du moyen d'agitation 3, ce qui permet de s'adapter à des boîtes de différentes profondeurs, correspondant à des contenances par exemple de 0, 5 L et de 1 L. In the case of containers laid down, the lid 2 is movable in translation relative to the elongate body 30, called the axis, of the stirring means 3, which makes it possible to adapt to boxes of different depths, corresponding to contents by example of 0, 5 L and 1 L.
Dans l'exemple illustré à la figure 1 , ledit couvercle 2 est équipé dudit moyen d'agitation 3 dont le corps allongé 30, tel que tige, est monté rotatif à travers le passage d'axe 20 du couvercle 2 et le joint d'étanchéité 1 . Ledit corps allongé 30 est équipé à, ou au voisinage de, une extrémité, d'au moins un organe d'agitation 31 tel que pale et à, ou au voisinage de, l'extrémité opposée, d'une partie de prise 32 pour l'entraînement en rotation dudit corps allongé 30 rotatif du moyen d'agitation 3. Ladite partie de prise peut être soit une fourchette d'entraînement pour les boîtes dites posées, soit un pignon d'entraînement pour les boîtes dites suspendues. En particulier, dans l'exemple illustré à la figure 1 , l'axe 30 porte une pale d'agitation 31 dont l'entraînement en rotation par l'intermédiaire du corps rotatif du moyen d'agitation permet l'agitation de la peinture contenue dans le pot. In the example illustrated in FIG. 1, said lid 2 is equipped with said stirring means 3 whose elongate body 30, such as rod, is rotatably mounted through the axle passage 20 of the lid 2 and the gasket. sealing 1. Said elongate body 30 is equipped at or near one end with at least one stirring member 31, such as a blade, and at or near the opposite end, a grip portion 32 for the rotary drive of said rotatable elongated body of the stirring means 3. Said gripping portion may be either a drive fork for the so-called put boxes, or a drive gear for the so-called suspended boxes. In particular, in the example illustrated in Figure 1, the axis 30 carries a stirring blade 31, the rotary drive through the rotating body of the stirring means allows the stirring of the paint contained in the pot.
De manière caractéristique à l'invention, la face périphérique interne dudit joint 1 d'étanchéité annulaire comprend une lèvre hélicoïdale 120. In characteristic manner to the invention, the inner peripheral face of said annular seal 1 comprises a helical lip 120.
Autrement dit, le joint d'étanchéité 1 est positionné dans un logement 21 ménagé dans le passage d'axe 20, ledit logement 21 dudit joint étant coaxial au passage d'axe 20 et situé côté face inférieure, c'est-à-dire côté face orientée vers la face intérieure du récipient ou face opposée à la face supérieure dudit couvercle équipée du mécanisme d'obturation du bec verseur. En particulier, le logement 21 est formé par un épaulement dans le passage d'axe 20 de sorte que led it logement débouche côté face inférieure du couvercle, ce qui permet une introduction et une extraction du joint par rapport à son logement depuis la face inférieure du couvercle. In other words, the seal 1 is positioned in a housing 21 formed in the axis passage 20, said housing 21 of said seal being coaxial with the axis passage 20 and located on the lower face side, that is to say face side facing the inner face of the container or face opposite to the face upper of said lid equipped with the closing mechanism of the spout. In particular, the housing 21 is formed by a shoulder in the axis passage 20 so that it housing opens on the underside of the lid, allowing introduction and extraction of the seal relative to its housing from the underside of the lid.
Le diamètre intérieur dudit joint annulaire 1 , pris au niveau de la ligne sommet du filet, qu i assure un léger serrage sur le corps al longé 30 du moyen d'agitation 3, est de préférence sensiblement inférieur au diamètre intérieur de la paroi de la partie 23 du passage d'axe 20 destinée au guidage en rotation avec jeu du corps allongé 30 du moyen d'agitation 3. The inner diameter of said annular seal 1, taken at the top line of the thread, which provides a slight clamping on the longitudinal body 30 of the stirring means 3, is preferably substantially smaller than the inside diameter of the wall of the part 23 of the axis passage 20 for guiding in rotation with play of the elongate body 30 of the stirring means 3.
Le joint annulaire 1 est un joint à deux parois périphériques 10, 1 1 reliées l'une à l'autre par une l iaison souple 101 . Lesdites parois dites respectivement interne 1 1 et externe 10, sensiblement coaxiales, sont écartées l'une de l'autre et reliées l'une à l'autre par une liaison souple 101 de type pont s'étendant, de préférence, à mi-hauteur desdites parois, dans le plan circonférentiel médian desdites parois. La liaison souple 101 de type pont forme une plateforme circulaire reliant lesdites parois entre elles. La double paroi présente en coupe transversale une forme en H. The annular seal 1 is a seal with two peripheral walls 10, 11 connected to each other by a flexible connection 101. Said so-called inner walls 1 1 and outer 10, substantially coaxial, are spaced from each other and connected to each other by a bridge-type flexible link 101 extending, preferably, half way height of said walls, in the median circumferential plane of said walls. The bridge-type flexible link 101 forms a circular platform connecting said walls to each other. The double wall has a cross section H-shaped.
La liaison souple 101 , déformable élastiquement, permet un bon centrage du corps allongé 30 de moyen d'agitation 3 à travers le joint 1 et le passage d'axe 20. En particulier, ladite liaison souple 101 permet l'auto-alignement entre le passage d'axe 20, ou palier, du couvercle 2 et la lèvre hélicoïdale 120 du joint d'étanchéité 1 lors de l'introduction du corps allongé 30 d u moyen d e d'agitation 3 à travers le passage d'axe 20 et le joint d'étanchéité 1 . The flexible link 101, elastically deformable, allows a good centering of the elongate body 30 of stirring means 3 through the seal 1 and the axis passage 20. In particular, said flexible connection 101 allows the self-alignment between the passage 20, or bearing, of the cover 2 and the helical lip 120 of the seal 1 during the introduction of the elongate body 30 of the stirring means 3 through the shaft passage 20 and the seal sealing 1.
La liaison souple 101 , permet de plus la dissociation des parois externe 10 et interne 1 1 qui ont des fonctions différentes. La paroi 1 0 a pour fonction le maintien par serrage à force du joint 1 dans son logement 21 . La paroi 1 1 a pour fonction l'étanchéité par serrage léger sur le corps allongé 30 du moyen d'agitation 3. Comme illustré plus particul ièrement à la figure 2, la lèvre hélicoïdale 120 comprend une pluralité de spires 121 , 122, 123, 124 formant le filet hélicoïdal de la lèvre hélicoïdale 120 du joint d'étanchéité . The flexible connection 101, furthermore allows the dissociation of the outer 10 and inner 1 1 walls which have different functions. The wall 1 0 has the function of holding by force tightening of the gasket 1 in its housing 21. The wall 11 serves the purpose of sealing by light clamping on the elongate body 30 of the stirring means 3. As illustrated more particularly in FIG. 2, the helical lip 120 comprises a plurality of turns 121, 122, 123, 124 forming the helical thread of the helical lip 120 of the seal.
Les spires 121 , 122, 123, 124 sont espacées axialement les unes des autres pour délimiter entre elles une gorge 12 en hélice. Ainsi, un liquide qui se serait introduit entre le joint 1 et le corps allongé 30 du moyen d'agitation 3 s'écoule dans ladite gorge 2 et retombe par gravité dans le pot de peinture 4 en parcourant ledit chemin en hélice. Le refoulement dudit liquide éventuellement monté dans la gorge en hélice 12 est également amélioré par la rotation du moyen d'agitation 3. L'orientation de la lèvre hélicoïdale 1 20 est définie en fonction du sens de rotation du corps allongé 30 du moyen d'agitation pour participer au refoulement dudit liquide vers l'intérieur du récipient. Lorsque le corps allongé 30 du moyen d'agitation 3 est destiné à être tourné en sens horaire, le filet hélicoïdal correspond à un filetage à droite. A l'inverse, lorsque le corps allongé 30 est destiné à être tourné en sens anti-horaire, le filet hél icoïdal correspond à un filetage à gauche. On entend par filetage à droite, respectivement à gauche, un filet ou filetage qui, dans la vue axiale, recule en tournant dans le sens horaire, respectivement dans le sens anti-horaire. The turns 121, 122, 123, 124 are spaced axially from each other to delimit between them a groove 12 helically. Thus, a liquid which would have been introduced between the seal 1 and the elongate body 30 of the stirring means 3 flows into said groove 2 and falls by gravity into the paint pot 4 by running along said helical path. The discharge of said liquid possibly mounted in the helical groove 12 is also improved by the rotation of the stirring means 3. The orientation of the helical lip 1 20 is defined according to the direction of rotation of the elongate body 30 of the agitation to participate in the discharge of said liquid to the interior of the container. When the elongate body 30 of the stirring means 3 is to be rotated clockwise, the helical thread corresponds to a right-hand thread. Conversely, when the elongate body 30 is intended to be turned counterclockwise, the helical icicle corresponds to a left-hand thread. Thread on the right, respectively on the left, means a thread or thread which, in the axial view, moves back by turning in the clockwise direction, respectively in the counter-clockwise direction.
La face périphérique interne dudit joint 1 d'étanchéité comprend également une lèvre d'étanchéité circulaire 13 située à proximité de la face d'ouverture dite supérieure du joint 1 d'étanchéité annulaire opposée à celle, dite inférieure, destinée à être orientée côté récipient 4. Autrement d it, ladite lèvre d'étanchéité circulaire 13 est située en partie supérieure du joint 1 , à l'état monté dudit joint 1 dans le couvercle 2 qui ferme le récipient 4. Cette lèvre circulaire 13 réalise la fermeture de la gorge 12 formée par la lèvre hélicoïdale 1 20 en partie supérieure. Elle permet ainsi d'assurer l'étanchéité statique aux vapeurs de solvant ainsi qu'aux liquides. The inner peripheral face of said seal 1 also comprises a circular sealing lip 13 located near the so-called upper opening face of the annular sealing gasket 1 opposite that, said lower, intended to be oriented container side 4. Otherwise, said circular sealing lip 13 is located in the upper part of the gasket 1, in the mounted state of said gasket 1 in the lid 2 which closes the container 4. This circular lip 13 closes the groove 12 formed by the helical lip 1 20 in the upper part. It thus makes it possible to ensure static sealing against solvent vapors as well as liquids.
Ledit joint 1 d'étanchéité annulaire est réalisé en un matériau thermoplastique, tel qu'un élastomère thermoplastique. Said annular seal 1 is made of a thermoplastic material, such as a thermoplastic elastomer.
La présente invention n'est nullement limitée aux modes de réalisation décrits et représentés, mais l'homme du métier saura y apporter toute variante conforme à son esprit. The present invention is not limited to the embodiments described and shown, but the skilled person will be able to make any variant within his mind.
